Ellaktor Group

What Ellaktor Group does

Ellaktor Group is a Greek publicly listed infrastructure conglomerate (Athens Exchange ticker: ELLAKTOR) with origins dating to 1954, operating through wholly-owned subsidiaries across construction, real estate development, environmental services, and hospitality. Its core construction arm, AKTOR, executes large-scale public infrastructure projects such as the Doha Metro Gold Line in Qatar, while R.E.D.S. handles property development and management, HELECTOR focuses on waste management and environmental engineering, and HESTIA operates luxury accommodations and marina developments. The group is headquartered in Nea Kifissia, Athens, and historically operated renewable energy (EL.TECH. ANEMOS, merged 2019 and spun off 2022) and infrastructure concessions (AKTOR Concessions, sold in 2025).

The company generates revenue primarily through project-based contracts with governments and large institutional clients, supplemented by transaction-based real estate sales and recurring hospitality income. Capital structure is anchored by a €670 million High Yield Green Bond (issued 2019–2020 through Cyprus-incorporated subsidiary ELLAKTOR VALUE PLC, rated B+/B-), which refinanced legacy indebtedness and was the largest High Yield Green Bond in Europe for 2019. Go-to-market is enterprise field sales targeting sovereign and institutional counterparties; the group is ranked 100th globally among construction groups per Deloitte's Global Powers of Construction 2020.

The corporate profile reflects a multi-year restructuring cycle: a 2019 merger with renewable energy subsidiary EL.TECH. ANEMOS, a 2021 share capital increase through preemptive rights, a 2022 spin-off of the RES sector, and the 2025 divestiture of AKTOR Concessions. Major shareholders include AtlasInvest, Reggeborgh Investment, and Motor Oil, with ongoing capital-return activities (dividends, buybacks) signaling a shift toward a leaner, core-construction-focused portfolio rather than diversified expansion.
